In August 2009, ISAAC was relocated from UT1 to UT3 to adjust the difference in the pressure factor of the two telescopes. The move went more smoothly than expected and the instrument was delivered in a very good state. A short report on the event is presented.

AA(ESO) AB(ESO) AC(ESO)Abstract:
The European Extremely Large Telescope is in its detailed design phase until the end of 2010. During this period, the telescope design is being consolidated and instrument and operation concepts are being studied. The scientific users are feeding back requirements into the project in numerous ways. One of them, the Design Reference Science Plan, was an opportunity for the entire community to provide direct feedback to the project. Here, we summarise the first results from this study. The full report will appear in the first half of 2010.References:

AA(ESO)Abstract:
In the 1980s and 1990s, the developments in sensitivity, size, and effective image quality of semiconductor detectors progressed faster and with lower cost than any equivalent increase in the geometrical light-collecting power of optical/infrared telescopes could have achieved. Now, in the era of Extra Large Telescopes, where light-collecting power is again increasing and ever more sophisticated space-borne instruments are in preparation, the growing maturity of detectors still forms an important cornerstone of these large investments. The recent workshop brought together many of the world’s leading detector developers, producers and users, as well as astronomers, to exchange ideas, questions and solutions with the aim of enabling detector systems to optimally support the exciting astronomy projects of the future.References:
